MAoHInE FOR use IN THE MANUFACTURE OF BOOTS Ann sHoEs,

Specification of Letters Patent.

Serial No. 376,600.

To all whom it may concern:

Bait known that I, EMERY BAYARD, a citizen ofv the United States, residing at Rochester, in the county of Monroe and State of New York, have invented certain Improvements in Machines for Use in the Manufacture of Boots and Shoes, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures. r I

This invention relates to machines for use in shaping shoes and particularly to a machine designed for performing the operation known as blocking a shoe.

The object of this operation is to shape the upper on the side of the shoe at and adjacent to the edge of the shoe bottom into conformity with the contour of the side face of the last and to remove wrinkles or inequalities in this portion of the upper. It is desirable that in this blocking operation the shoe be so treated as to avoid drawing the upper back-from the edge of the last over which it was stretched in lasting, and preferably the blocking operation will be so performed as to tend to workthe upper on the side of the last towardthe edge of the shoe.

By so doing the upper is drawn more snugly to the last and the edge of the shoe may be shaped. For the purpose of steadying the shoeand supporting it in proper relation to the blockingtool a table or support is employed against which the shoe bottom is rested.

A feature of this presentinvention consists in providing, in amachine for the purpose stated, a vibrating tool and a rest for supporting the shoe relatively arranged to causethe blows of the tool on the side of the shoe .to be receivedfrom a direction at a slight inclination to the plane of the shoe bottom. Preferably provision is made for varying this inclination by mounting the table so that it may have an angular adjustforms a rest or anvil-between which and the blocking tool the edgeofthe shoe is shaped on its side and bottom faces.

In the preferred embodiment of the in vention provision is made in" a machine hav' for this downward movement constitutes a, very important feature of the invention.-

Asshown, the blocking tool is yieldingly mounted in an actuator which moves in a path inclined toward the shoe bottom:-

pr Patented April 13, 19091, Original application filed February ,2, 1907, Serial No. 355,509. Divided and this application filed May 31, 1907.'

When theadvance of the tool is arrested by its engagement with the shoe the actuator continues its movement and by reason of theinclinationof its path forcesthe tool to move downwardly along the side of the shoe.-

This works the upper on the side of the shoe toward the edge. One advantage of this operation is that it tends to form the upper in the rand crease, made by the upper and sole or welt, and overcome the gaping of the.

crease sometimes seen in shoes. If the shoe being operateduponhasan attached sole or welt the edge of whichprojects ,outwardiv beyond the side of the-last, the table will preferably be so positioned vertically that the welt or sole may extend between the table and the lower edge of the blocking tool. This arrangement has the advantage ;of

enabling the side of the shoe tobe' treated without danger of the edge of the sole or welt being struck by the tooland mutilated; Another important advantage of the -de scribed construction is that the blocking tool which may be a hammer head-having an outer end face for engaging the upper may have also a lower working face for beating the upper face of the sole or welt at the same timethat the upper is being blocked. 1

This 'may be desirable in any kind. of shoe,

but is especially advantageous in treating turn shoes, and also welt shoes before the soles are applied, for the action of the hammer beats out the welt or the projecting edge of the turn sole giving to it the shape and relative position with reference to the shoe that is required.

A further feature of the invention may, therefore, be stated to consist in providing a hammer shaped to engage the upper face of a Welt or sole edge by one face and the adjacent upper on the side of the shoe by the other face, and actuating mechanism for vibrating the hammer to beat both said portions of the shoe with its appropriate faces.

These and other features of the invention will be explained more fully in connection with the following description of the machine and will be pointed out in the claims.

The drawings illustrate a preferred embodiment of the machine.

Figure 1 is a side view, partly in section, on the line 11 of 2. Fig. 2 is an end view; l -ig. 3 is a plan view; and Efig. 4 is a detail view illustrating by full and dotted lines different positions which the hammer may assume during its operation.

A stand 2 has bearing for a shaft 3, on which is mounted a cam 4, shown as a threesided cam arranged to engage the lower arm of a lever 5. The lever is mounted on a fulcrum 8 in suitable bearings 7 and is held by a spring 6 with its lower end. yieldingly pressed against the cam. The upper end of the lever is recessed to receive the stem 10 and the shank of the blocking hammer 12. The recess is formed to permit these parts to slide lengthwise but to prevent any lateral move ment of the blocking hammer. The backward sliding movement of the hammer takes place against a spring 15 abutting at its rear end against an adjustable sleeve nut 14. The table or work rest upon which the shoe is supported comprises a standard 16 secured in adjusted position upon the stand 2 by a locking device 18. Upon the standard is mounted a head 20 having a stem 22 extending downwardly into the standard and secured in vertical position by the binding nut 24. The table 25 has a depending arm 26 which is connected to the head 20 by the pin 28. The arm 26 has also a segmental slot 30 through which extends a binding screw 32. By this arrangement the table 25 may not only be adjusted vertically, but may also be adjusted angularly about the pivot 28 and secured in angular position by the screw 32. The hammer is prevented from turning in the lever by means of a pin 36 which is guided in a groove in the lever. The hammer has on its front end a striking face 38 designed to engage the 11 per on the side of the shoe and on its lower edge is formed with a striking face 40 adapted to engage the upper face of the portion 8 of the sole or welt which projects beyond the up er of the shoe.

n the use of the machine the table 25 will .eration.

preferably be adjusted vertically and angularly wiih relation to the hammer sutstan-- tially as shown in Pig. 1. in this position the projecting edge of the sole or welt may extend between the table and the lower face 40 of the hammer, thus allowing the hammer to beat the side of the shoe for blocking the shoe without danger of striking the edge face of the sole. The spring 15 permits the hammer lever to continue its movement after the hammer head contacts with the side of the shoe in the forward movement of the hammer. It will lie understood, however, and this is brought out more especially in 4, that the movement of the upper end of the hammer lever has a downward component. The hammer head cannot yield vertically in the lever and, therefore, it receives a positive downward movement along the upper on the side of the shoe during the last portion of each stroke. This causes the hammer to force the u per toward the edge of the shoe bottom and the table cooperates with the hammer in shaping the edge of the shoe as will be obvious if the shoe being operated upon has no sole or welt. If the shoe is provided with a sole or welt the hammer tends to work the upper toward and into the rand crease and prevent the crease from gaping. If the table is adjusted to the proper height with relation to the hantin'ier the lower side of the hammer head, which is of a breadth to form. a striking face as is shown in ligs. l and 4, strikes the upper face of the sole or welt as said head is actuated downwardl during the last portion of the stroke of its lever. T he hammer may thus be employed to beat out a welt or the projecting edge of a soleas, for example, the sole of a turn shoe which has been more or less distorted. in the turning op- It will be observed that the hammer when. used as described has two movcments, one of which is in a path inclined slightly to the horizontal and by which it beats the upper on the side of the shoe, and the other of which is in an approximately vertical plane. ln this last movement the hammer beats the upper face of the sole or welt and also rubs the upper toward the ed go of the shoe.
